BuddhaNexus is a text-matching database with visualization capabilities that draws its data from Buddhist literary corpora in Pāli, Sanskrit, Tibetan, and Chinese. It allows users to conduct intralingual searches (e.g. searching among texts in Chinese only) of individual volumes for textual matches across the collection in question. Additionally, users are also able to produce Sankey visualizations of connections within different collections in the same language, which offers an intertextual view across collections, sections within collections, and within single texts.
